[Bug 1825718] Re: Touchpad not detecting in Linux
Andan,
Can you please test latest mainline kernel? I think this commit can fix your
issue:
commit 670784fb4ebe54434e263837390e358405031d9e

pinctrl: intel: Clear interrupt status in mask/unmask callback
Commit a939bb57cd47 ("pinctrl: intel: implement gpio_irq_enable") was
added because clearing interrupt status bit is required to avoid
unexpected behavior.
Turns out the unmask callback also needs the fix, which can solve weird
IRQ triggering issues on I2C touchpad ELAN1200.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- disco' to 'verification-done-disco'. If the problem still exists, change the tag 'verification-needed-disco' to 'verification-failed-disco'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1825718] Re: Touchpad not detecting in Linux
Hi Kai-Heng Feng,
I have a laptop with the same problem. It's a SCHNEIDER SCL142ALM.
I have compiled the ubuntu kernel modifying the
"i2c_hid_dmi_desc_override_table" to add:
{
.ident = "SCHNEIDER SCL142ALM",
.matches = {
DMI_EXACT_MATCH(DMI_SYS_VENDOR, "SCHNEIDER"),
DMI_EXACT_MATCH(DMI_PRODUCT_NAME, "SCL142ALM"),
},
.driver_data = (void *)_desc
},
And it's working fine.
Probably I could ask to include it in the next kernel version, but I
think that it's not a good option to modify the kernel for every new
vendor and model that decides to use this device.
It would be possible to add some parameter in the bootargs like for
example psmouse.proto=sipodev and then use the i2c-hid-dmi-quirks?
In the meanwhile, please can you add the SCHNEIDER SCL142ALM to the
override list?
Than you.
